Book Discussion Scheme is a charity on Colombo Street in Sydenham, Christchurch, rated 4.8 from 9 reviews. Rather than running as a public-facing shop, the Book Discussion Scheme supplies sets of books, multiple copies of the same title, plus discussion notes, to community reading groups right around New Zealand, so a group can read and talk through the same book together rather than everyone sourcing their own copy separately. Groups typically join through a subscription, receiving a rotating supply of book sets over the course of a year, with new titles swapped in as previous ones get returned, which keeps the reading fresh without a group needing to buy books outright. Joining usually happens by finding or starting a local reading group rather than turning up in person looking for a single book, since the scheme is built around groups rather than individual borrowers. On Colombo Street in Sydenham, this is where that national scheme is based.
